Products Description of Thiabendazole CAS#148-79-8
Thiabendazole, commercially available under names including Teketol, is a highly efficacious broad-spectrum fungicide employed globally. It displays systemic apical conductivity, meaning it is translocated upward in plants but does not move downward to the base. The compound provides long-lasting protective effects and is known to exhibit cross-resistance with other fungicides of the benzimidazole class. Its inhibitory activity spans multiple fungal groups, such as Ascomycetes, Basidiomycetes, and Deuteromycetes. Thiabendazole finds extensive application in agriculture for the prevention and control of fungal diseases in crops, and in post-harvest scenarios for the preservation of fruits and vegetables.

Product Application of Thiabendazole CAS#148-79-8
The fungicide is effective against a variety of fungal diseases and root rot in crops, delivering both preventive and therapeutic benefits. Furthermore, it finds wide application in controlling post-harvest storage diseases of fruits such as citrus, apples, pears, and bananas. For post-harvest treatment, it is commonly used as a solution at concentrations typically ranging from 500 to 1000 mg/L or 700 to 1500 mg/L, depending on the specific fruit.
Globally, Thiabendazole is recognized as a highly efficient, broad-spectrum fungicide with extensive international utilization.
